随着冻土带生态系统对北极迅速变暖的反应，卫星记录表明大范围的绿化。这一观点强调了解释复杂的北极绿化趋势的挑战，并通过结合生态和遥感方法为未来的研究提供了方向。随着北极变暖，植被正在做出反应，卫星测量表明高纬度地区广泛的绿化。这种“北极绿化”是世界上对全球气候变化最重要的大规模生态反应之一。然而，人们正在形成一个共识，即所谓的北极绿化和布朗宁趋势的根本原因和未来动态比之前想象的更加复杂、多变，并且本质上取决于规模。在这里，我们总结了观察和解释高纬度绿化的复杂性，以确定未来研究的优先事项。将卫星和近距离遥感与现场数据结合起来，同时考虑到不确定性和尺度问题，将推动对过去、现在和未来北极植被变化的研究。
As tundra ecosystems respond to rapid Arctic warming, satellite records suggest a widespread greening. This Perspective highlights the challenges of interpreting complex Arctic greening trends and provides direction for future research by combining ecological and remote sensing approaches.As the Arctic warms, vegetation is responding, and satellite measures indicate widespread greening at high latitudes. This 'greening of the Arctic' is among the world's most important large-scale ecological responses to global climate change. However, a consensus is emerging that the underlying causes and future dynamics of so-called Arctic greening and browning trends are more complex, variable and inherently scale-dependent than previously thought. Here we summarize the complexities of observing and interpreting high-latitude greening to identify priorities for future research. Incorporating satellite and proximal remote sensing with in-situ data, while accounting for uncertainties and scale issues, will advance the study of past, present and future Arctic vegetation change.
